Formation of mammalian erythrocytes: chromatin condensation and enucleation [PDF]

open access: yes, 2011
In all vertebrates, the cell nucleus becomes highly condensed and transcriptionally inactive during the final stages of red cell biogenesis. Enucleation, the process by which the nucleus is extruded by budding off from the erythroblast, is unique to ...

Discovery of a Novel DNMT1 Inhibitor with Improved Efficacy in Treating β‐Thalassemia

open access: yesAdvanced Science, EarlyView.
Context of Research: β‐thalassemia affects millions worldwide. DNMT inhibitors are effective HbF‐inducers that benefit patients with β‐thalassemia. Existing DNMT inhibitors are not approved for β‐thalassemia treatment due to dose‐limiting toxicity.What We Find: DMT207 traps DNMT1 into helix‐kinked inactive conformation and enhances its interaction with

Histone deacetylase 2 is required for chromatin condensation and subsequent enucleation of cultured mouse fetal erythroblasts

open access: yesHaematologica, 2010
Background During the final stages of differentiation of mammalian erythroid cells, the chromatin is condensed and enucleated. We previously reported that Rac GTPases and their downstream target, mammalian homolog of Drosophila diaphanous 2 (mDia2), are ...

DNA Nanoflower LYTACs Enable Efficient VEGF Degradation and Verteporfin Loading for Combined Therapy of Wet Age‐Related Macular Degeneration

open access: yesAdvanced Science, EarlyView.
An integrated approach that combines a DNA nanoflower VEGF degrader with photodynamic therapy is developed for the treatment of wet age‐related macular degeneration, which reduces the risk of VEGF reactivation‐induced CNV recurrence and minimizes the systemic side effects associated with photodynamic therapy.

Management of inflammatory dentigerous cysts in children : report of two cases [PDF]

open access: yes, 2010
Inflammatory dentigerous cysts are usually associated with a carious or non-vital primary tooth. Consequently they are found in children with a mixed dentition.

Robotic Partial Nephrectomy for a Peripheral Renal Tumor [PDF]

open access: yes, 2018
Partial nephrectomy (PN) is the preferred surgical treatment for T1 renal tumors whenever technically feasible. When properly performed, it allows preservation of nephron mass without compromising oncologic outcomes.

Photothermal Transport for Guiding Nanoparticles Through the Vitreous Humor

open access: yesAdvanced Science, EarlyView.
Nanosecond laser irradiation of the clinically approved dye indocyanine green (ICG) enables light‐guided nanoparticle transport within the vitreous humor. The combined use of ICG and pulsed laser illumination induces localized convection and thermophoresis, directing particles toward illuminated regions.
